Hi, all,

 

We encountered a critical issue: internal storage cannot be mounted after factory reset.

 

Internal storage is correct after I download images via MFGTool, and mount info is:

rootfs / rootfs ro,relatime 0 0

tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0

devpts /dev/pts devpts rw,relatime,mode=600 0 0

proc /proc proc rw,relatime 0 0

sysfs /sys sysfs rw,relatime 0 0

none /acct cgroup rw,relatime,cpuacct 0 0

tmpfs /mnt/secure tmpfs rw,relatime,mode=700 0 0

tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0

tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0

tmpfs /mnt/shm tmpfs rw,relatime,size=1024k,mode=775,uid=1000,gid=1003 0 0

none /dev/cpuctl cgroup rw,relatime,cpu 0 0

/dev/block/mmcblk0p5 /system ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

/dev/block/mmcblk0p4 /data ext4 rw,nosuid,nodev,noatime,nodiratime,errors=panic,user_xattr,acl,barrier=1,nomblk_io_submit,data=ordered,noauto_da_alloc 0 0

/dev/block/mmcblk0p6 /cache ext4 rw,nosuid,nodev,relatime,user_xattr,acl,barrier=1,nomblk_io_submit,data=ordered 0 0

/dev/block/mmcblk0p7 /device ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

/dev/block/mmcblk0p8 /vendor ext4 rw,nosuid,nodev,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

none /sys/kernel/debug debugfs rw,relatime 0 0

/dev/fuse /mnt/shell/emulated fuse rw,nosuid,nodev,relatime,user_id=1023,group_id=1023,default_permissions,allow_other 0 0

/dev/block/vold/179:25 /mnt/extsd vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

 

But internal storage cannot be mounted after factory reset, the mount info is:

rootfs / rootfs ro,relatime 0 0

tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0

devpts /dev/pts devpts rw,relatime,mode=600 0 0

proc /proc proc rw,relatime 0 0

sysfs /sys sysfs rw,relatime 0 0

none /acct cgroup rw,relatime,cpuacct 0 0

tmpfs /mnt/secure tmpfs rw,relatime,mode=700 0 0

tmpfs /mnt/asec tmpfs rw,relatime,mode=755,gid=1000 0 0

tmpfs /mnt/obb tmpfs rw,relatime,mode=755,gid=1000 0 0

tmpfs /mnt/shm tmpfs rw,relatime,size=1024k,mode=775,uid=1000,gid=1003 0 0

none /dev/cpuctl cgroup rw,relatime,cpu 0 0

/dev/block/mmcblk0p5 /system ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

/dev/block/mmcblk0p4 /data ext4 rw,nosuid,nodev,noatime,nodiratime,errors=panic,user_xattr,acl,barrier=1,nomblk_io_submit,data=ordered,noauto_da_alloc 0 0

/dev/block/mmcblk0p6 /cache ext4 rw,nosuid,nodev,relatime,user_xattr,acl,barrier=1,nomblk_io_submit,data=ordered 0 0

/dev/block/mmcblk0p7 /device ext4 ro,nosuid,nodev,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

none /sys/kernel/debug debugfs rw,relatime 0 0

/dev/block/vold/179:25 /mnt/extsd vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

 

There is no /dev/fuse.

 

Anyone can help me?

 

Thanks.
